ipplcation filed April 252.

I@ all i12/wm it may concern Be it known that l, Rnnonr W. Bean, tir., :L subject of the Emperor of llermany, residinget Buffalo, in the county of llrie and State of New York, have invented certain new and useful Improvements in l'iose Couplings, of which the following is a speen tication.

My invention relates to improvements in hose couplings, and more particularly' to quick acting hose coupling such as is employed for coupling the ends of consecutive lengths ot fire hose. i

The Object of my invention is to provide a simple and effective coupling whereby the ends of adjoining lengths ot hose may he quickly united or disconnected without the necessity of turning the respective lengths of. hose relatively'.

A further object is the provision of at coupling of this type having few parts und which requires only the proper relative placement of one )art with respect to enother and the actuation of a single locking element.

The invention consists in the novel i'eatures of construction :ind in the arrangement and combination of parts to be hereinafter described and particularly pointed out in the subjoined claims.

In the drawings-Figure l is an elevation. of a hose showing two adjoining lengths coupled together hy means of my improved coupling'. Fig. 2 is :i longitudinal sect' through the coupling and the adjacent ends of two adjoining hose lengths. Fig. is a longitudinal section through the coupling showing the two main members disconnected. Fig. i is a transverse section taken on line 4 4, Fig. Fig. 5 is :i section taken on line 55, Fig. Fig. 6 is a detached perspective viei' of the locking member.

Reference being had to the drawings in detail, the reference numeral 7 designates two adjoining hose lengths coupled together by means of my improved coupling S.

The coupling comprises two mein members 9, l0, which are preferably in the iorni of tubes or hollow cylinders, one of which is counterhor'ed, :is at l1E to receive the ndjzicent end of the other, thus these niemhers are in the form of male und female parts, one fitting partly into the other. iy counterboring the member' 9, an internal shoulder 12 is provided, against which is ,seated a gasket lf3, und the inner end of Specication of Letters Patent,

member il) is adapted to be forcibly pressed :against said-gasket so as to make a watertight joint between the two members. The mule member has an external annular flange .Il between its ends which, as shown, is stepped, and itting around said unile member is a locking member l5 in the form of a ring, the opening of said locking member being double counterbored to correspond to the stepped l'lzinge il on the mele member. The i'iange il enters saidv counterbored Iopening` so as to provide a plurality ot' smooth bearing surfaces which tend to minimize the tendency ot' the purts wearing, due to one turning upon the other and this construction also renders the parts free in action.

rlhe female member has elongated lugs or extensions i6 at dizunetricelly opposite points, each of said extensions having a lougitudinal bore 1T Jformed therein. lidably retained in said bores are yielding locking pins or studs i8. llach ot' the hores li' is enlarged et opposite ends to provide oppositely-facing shoulders 19, 2U. Arranged in one ot' seid enlarged portions and surround` ing' the pin or stud 18 is a. coiled spring 2l which bears with one end against the shoulder l5) and with its other end lageinst a nut 22 threaded onto the pin or stud 1S, said nut being coniined within the bore and made adjustable on the pin or stud so as to regulate 'the tension of the sprinfr. Against the other shoulder i() is adapted to hear a collar or ilange 'i3 formed on the pin 18. This collar limits'the morement ol.t said pininrone direction7 such movement being caused by the pension ot' spiral spring '21 surrounding the pin. The opposite pins are placed under euual tension so that they will act in unison` und exert equal pressure in coupling the members ot' the couplingtogetherf Said ionizing' pins project beyond the outer end l'are oi the female member il and are provided with enlargements or heads 2l at their proiectiiigends.

"ihe locking member or ring 15 is provided with segmental slots 25, each slot heing enlarged :it one end, as at 26, the enlargements heing of a size to permit the heads 24 of the pins 18 to be passed therethrough. The outer face of the locking member is provided at opposite sides of the sluts with inclined or Wedgesshaped portions 2T which ride under and in Contact with the heads of the pins when 'turning the locking member. This movement of the .heads l ot' the locking pins.

locking member causes compression ol the springs l bv reason otl the locking pinslbeing moved outwardly.y such movement being continued until the pins` reach the opposite endsI et' the slots` at which pointsthe highest elevation otI the inclined or wedge-shaped portions T are reached. and directly bevond deln'essions '3S are formed to receive the When the heads are seated in the depressions. accidental unrmlpling ol vthe parts cannot talee place, since the springs 'il arc placed under sul'lieient tension to prevent outward movement oi the locking pins Amllicientlv to, cause the heads thereof to ride onto the wedgeshaped or inclined portions 2i' without suflicient manual cli'ort being exerted to cause such action. rThe outer c vlindrieal ends of the main members have the hose sections 7 secured thereto b v means of clips or other suitable means.

In order to couple two lengths of a hose together, it is simply necessary to insert the male member l0v partlyvv into the female member until the stepped flange of the male mei'nbci' closely approaches or bears against; thi'i'outer, face ot' the female member. The lockingr ring 15 is then positioned to enter the locking pins in these-ginental slots and asthe collars or flanges 223 ot" said pins holdthe latter projected a certain distance so that theheads of the .same are positioned toiride upon the inclined er erigir-shaped portions of said slots, it is only necessaryY to rotate they locking ring.` whereupon the members'l and l0 are pressed firmlyl into position7 they being retained by the locking pins which are held properly Seated against Jthe ringby said springs. Reverse action of the parts in onliy necessary in order to discenneet the hose len gths.`
